Multiple threads posted today by me in various forums all relate around this concern.
Ok i bought a new B17 for my Trek 520 probably a month or more ago. Sure it was hard for a while and yes i was sore also for a while but i thought it was breaking in pretty well. I could see the dents appearing where my sit bones would be.
Late last week i went for my first trip to test out my gear. Day 1 i did 130km which included a very long and steep climb which really took it out of me. Anyhoo i camped one nite, then did another 80km the next day to my next location. Was a pretty hard ride where i found i was very sore for the first hour almost and then the pain sort of went away.
Anyhoo camped another nite then i had just a 70km ride home. Well the pain was shocking again for about another hour before it settled down. I got home on the Saturday morning and haven't been back on the bike since.
Even now almost a week later i can still feel my sit bones, they are getting better though.
On checking out my saddle closer they two dents are quite pronounced, probably more on one side than the other. My concern is that they are really far back on the saddle, and i suspect they overlap the rear metal support frame. If you run your finger along one dent you can actually feel the metal frame under it.
Which i'm wondering if this is the cause of my discomfort?
The Trek is quite a big size so it's a roomy frame, i have the saddle back as far as the rails will allow and yet my sit marks are still really towards the back end of the saddle.
is this normal?
